I’m Serge Skoredin (SergeiSkv) — Go performance engineer, author and mentor. Based in Berlin, I help developers and companies build fast, efficient, maintainable Go systems by focusing on real performance issues, deep optimizations, and clean code. Through Skoredin.pro, I publish deep dives into areas like: • CPU cache optimizations, data layout, false sharing, and memory efficiency • Benchmarking, profiling, and performance debugging • Real-world evaluation of AI coding tools for Go (what works, what fails) • Best practices in API design, concurrency, and systems architecture
